Congressman Ron Paul (R-TX) and his son, Kentucky Republican Rand Paul, made history this week. It is the first time that a son will be in the Senate while his father serves what will be his 10th term in the House of Representatives.

Both men are physicians, and while they may share the Rx pad of the Republican party, this pair doesn't always keep it in the family -- Ron Paul holds strong Libertarian views and Rand Paul has been a Tea Party favorite.

Elder Paul's presidential bid in 2008 had a lot of supporters online, but not many in most of the primaries. Interestingly, on Tuesday his son Rand received more votes for his Senate bid in Kentucky than his father did there two years ago -- and it was a wide margin. Then presidential candidate Ron Paul received 13,427 votes statewide. At final count, Rand garnered 755,061 votes Tuesday.

The Pauls replace an American political dynasty duo on Capitol Hill. Senator Ted Kennedy (D-MA), who died last year, and his congressman son Patrick Kennedy (D-RI), served at in both houses at the same time. Only months after his father's death, Patrick Kennedy decided to retire from Congress, leaving the nation's capital without a Kennedy in political office for the first time in more than 60 years.

The last time a son served in Congress at the same time as his father was in the nineteenth century when Henry Dodge of Wisconsin served in the Senate from 1848 to 1857; his son Augustus was a Senator from Iowa from 1855-1858.

House Speaker Nancy Pelosi is the daughter of Thomas D'Alesandro, Jr. (D-Md.), who served in the House from 1939 until 1947.
